For privacy purpose only then I will advise you to use p2p to remain anonymous as you may which, otherwise bestchange also has the feature you needed just visit bestchange.com and or exch. Please do your proper investigation on where you are sending your funds to buy the other coin you wanted.
Be very mindful on how you accept pm from any newbie or anyone as they can posse to be a trader or deal and got you scammed.

I’ve used Xchange a bunch of times recently. They only charge 1% for nearly instant trades, with no signup or KYC required.
